Over the past week, a comforting market assumption has completely unraveled. For nearly three weeks since the outbreak of the Iran conflict, markets had bet that energy supply disruptions would be brief, the Strait of Hormuz would reopen, and the Federal Reserve's rate-cutting cycle would resume as expected. This bet has now collapsed.
Global bond markets experienced a severe sell-off this week, gold posted its largest weekly decline since 1983, and U.S. stocks fell for a fourth consecutive week, marking the longest losing streak in a year. Concurrently, market pricing briefly reflected a 50% probability that the Fed's next move would be a rate hike, not a cut.
Mark Malek, Chief Investment Officer at Siebert Financial, characterized the week as a "moment of reckoning" – markets across the board finally began to face the reality that the conflict is not only a protracted war with an uncertain outcome but has also escalated into a worst-case scenario involving direct strikes on the region's critical energy infrastructure.
Meanwhile, cross-market stress is building at the fastest pace since last year's tariff shocks. According to a Bank of America index, trades in equities and credit built on rate-cut expectations are unwinding simultaneously, with emerging markets also under pressure. Analysis indicates the Iran conflict is no longer a one-off price shock but a persistent threat that investors, central bankers, and corporate leaders are forced to confront directly.
**Bond Market Rout and Gold's Collapse: A Fundamental Shift in Pricing Logic** The past week's severe downturn in global bond markets provided the most visible illustration of the current turmoil.
The yield on the 10-year U.S. Treasury note surged by 13.4 basis points in a single day, rising over 10 basis points for the week. The 5-year yield broke above 4% for the first time since July, and the yield curve flattened sharply.
European bond markets were not spared. The UK 10-year gilt yield rose 17.7 basis points over the week, touching 5% for the first time since 2008. Germany's 10-year bund yield reached a new high since 2011 at 3.043%, while Italy's 10-year yield climbed over 16 basis points for the week. The two-year German bond yield saw an even steeper increase of 23 basis points.
The collapse in gold was particularly striking. Spot gold fell over 10% for the week, and COMEX gold futures dropped more than 11%, recording their largest weekly decline since March 1983.
Analysis notes that the trigger for gold's sharp decline back then was also an oil crisis—Middle Eastern oil producers, facing reduced income from falling oil prices, were forced to sell gold reserves for cash. This historical parallel has sparked concerns about a repeat scenario.
Analysts partly attribute the recent gold price decline to emerging U.S. dollar funding pressures. Cross-currency basis swaps widened significantly this week, suggesting signs of dollar liquidity tightness. Gold has also resumed its negative correlation with real interest rates—as real rates climbed rapidly, gold came under pressure.
In the precious metals space, silver fell even more sharply, with COMEX silver futures down over 16% for the week. Industrial metals like copper, aluminum, and tin also declined across the board, with LME copper losing over 6.6% and falling below the $11,000 per tonne level.
An ETF tracking a combination of the S&P 500, long-term U.S. Treasuries, and gold recorded its worst combined weekly performance since the conflict began.
Priya Misra, a Portfolio Manager at JPMorgan Asset Management, offered a starker assessment:
"Risk premiums should be higher—this is the largest energy shock in history, with no simple fiscal, monetary, or energy policy responses available. Recession risk should be rising sharply. Equities and credit spreads have been too resilient, based on hopes that businesses and households can absorb the energy shock."
**The Fed's Dilemma: A Sudden Reversal in Monetary Policy Expectations** At the core of this reckoning is a sharp repricing of market expectations for the Federal Reserve's policy path.
The Fed held rates steady on Wednesday, with Chair Powell stating clearly that the oil price shock has made the inflation outlook too uncertain to provide a timeline for easing.
On Friday, Fed Governor Waller expressed caution about how high oil prices affect inflation but also noted that rate cuts would still be warranted if the labor market weakens. He acknowledged the conflict appears to be taking a more persistent turn, raising the risk of oil prices remaining elevated for longer.
The market's reaction was more aggressive. Current pricing indicates a 50% probability of a Fed rate hike within 2026—bond traders, who previously predominantly bet on cuts, are being forced to recalibrate their strategies as sentiment shifts rapidly.
Gennadiy Goldberg of TD Securities expressed skepticism:
"We disagree with the market's call for hikes. Soaring oil prices should lead the Fed to delay cuts due to stagflationary pressures. However, if the oil price increase is large enough, it could cause a financial conditions shock, potentially forcing the Fed to respond with cuts instead."
Michael Ball, a Bloomberg Macro Strategist, warned that the sudden repricing of monetary policy expectations triggered by the Iran conflict, alongside tightening financial conditions, risks turning a manageable pullback in the S&P 500 into a full-blown correction.
The European Central Bank faces an even trickier situation: energy-driven inflation is blocking the path for rate cuts, while a deteriorating growth outlook urgently requires accommodative policy—leaving the ECB similarly stuck in a difficult position.
**Wall Street Reprices for a 'Long War'** The true turning point for markets has been a fundamental change in investor expectations regarding the conflict's duration.
Signals from U.S. officials indicate the White House is deploying hundreds of additional Marines to the Middle East and evaluating options to seize or blockade Iran's Kharg Island oil export terminal, which handles about 90% of Iran's oil exports. The U.S. President first stated he did not want a ceasefire, then later said he was considering a gradual de-escalation of military action against Iran, while again pressuring military allies to join the conflict or assist in keeping the Strait of Hormuz open.
Jose Torres of Interactive Brokers stated bluntly:
"Investors initially thought the Iran war would end quickly, but as the confrontation escalates with no light at the end of the tunnel, the pain on Wall Street continues."
Christian Mueller-Glissmann, Head of Asset Allocation Research for Global Investment Research at Goldman Sachs, said:
"If this rates-energy shock persists or deepens, growth pricing across assets needs to move further in a pessimistic direction. Markets are not fully pricing growth risks at the moment, which partly explains why the decline in U.S. stocks hasn't been larger."
Garrett Melson, Portfolio Strategist at Natixis Investment Managers, noted the market is "incrementally pricing in longer and longer ripple effects day by day." He has recently reduced exposure to small-cap stocks while increasing allocations to large-cap growth and technology stocks.
Defensive adjustments at the institutional level are accelerating.
Societe Generale reduced its recommended allocation to global equities by 5 percentage points during Thursday's heightened volatility, simultaneously increasing its allocation to commodities. BCA Research advised clients to raise cash holdings and reduce equity exposure. Goldman Sachs Global Investment Research recommended a defensive posture, tactically shifting its three-month asset allocation to overweight cash, underweight credit, and neutral for other major asset classes.
Historical patterns show that based on data from over 30 geopolitical shocks since 1939, the U.S. stock market typically bottoms around the 15th trading day after the shock, with an average decline of just over 4%. The S&P 500 is currently down approximately 5.5% since the conflict began, corresponding to the 13th trading day. This places it in the historical window where the "worst news flow" and "greatest market damage" often coincide.
David Laut of Kerux Financial noted:
"The stock market remains in negative territory for the year and hit a new low for 2026 this week, suggesting the market may not have bottomed yet and is still digesting uncertainties around the duration of the Middle East conflict."
